Spinner

ion-spinner

The ion-spinner component provides a variety of animated SVG spinners.
Spinners enables you to give users feedback that the app is actively
processing/thinking/waiting/chillin’ out, or whatever you’d like it to indicate.
By default, the ion-refresher feature uses this spinner component while it's
the refresher is in the refreshing state.

Ionic offers a handful of spinners out of the box, and by default, it will use
the appropriate spinner for the platform on which it’s running.

The following code would use the default spinner for the platform it's
running from. If it's neither iOS or Android, it'll default to use ios.

<ion-spinner></ion-spinner>

By setting the name property, you can specify which predefined spinner to
use, no matter what the platform is.

<ion-spinner name="bubbles"></ion-spinner>

Styling SVG with CSS

One cool thing about SVG is its ability to be styled with CSS! One thing to note
is that some of the CSS properties on an SVG element have different names. For
example, SVG uses the term stroke instead of border, and fill instead
of background-color.
